Question

Brent needs to paint a logo made using two right triangles. The dimensions of the logo are shown below. What is the difference between the area of the large triangle and the area of the small triangle?
4.5 cm2
8.5 cm2
16.5 cm2
33.0 cm2

Answer 1

I LOVE the name of the logo creator, just saying ;)

A small = 1/2(2)(6) = 6 cm^2
A large = 1/2(5)(9) = 22.5 cm^2

Difference is 22.5 - 6 = 16.5 or C

Answer 2

Area of large triangle = 1/2 bh =1/2(5)(9) = 45/2 = 22.5
area of small triangle = 1/2 bh = 1/2(2)(6) = 12/2 = 6

the difference between the area of the large triangle and the area of the small triangle
= 
22.5 - 6 = 16.5
answer 
16.5 cm2
